FIG. 1 is a top plan view of an aircraft nagivation plotter showing my new design, the lower circular transparent disc having been rotated for exemplary purposes, so that 265° is indexed at the diamond on the subjacent opaque base plate and the arrows on the uppermost substantially semi-circular transparent plate point respectively to 115° and 295° on the underlying circular transparent disc;

FIG. 2 is an elevational view of one side edge, the elevational view of the opposite side edge being substantially a mirror image thereof;

FIG. 3 is an elevational view of one end edge of FIG. 4, the elevational view of the other end edge being substantially a mirror image thereof; and,

FIG. 4 is a bottom plan view. 

The ornamental design for an aircraft navigation plotter, as shown and described.
